</blockquote><h4><a name = "tag_000_005_462">&nbsp;</a>SYNOPSIS</h4><blockquote>

function is equivalent to

</blockquote><h4><a name = "tag_000_005_467">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
If the integer value returned by
<i>getchar()</i>
is stored into a variable of type
<b>char</b>
and then compared against
the integer constant EOF,
the comparison may never succeed,
because sign-extension of a variable of type
<b>char</b>
on widening to integer is implementation-dependent.
